Getting started improvements and ongoing design

Today I updated the getting started page of the TiltyIMU with a much nicer reference illustration for the Tilty Duo and Quad connections. It’s still cluttered, and probably not quite final, but it’s a lot better than the bullet point list I was using previously. Every connection available is labeled now, and the 3.3v only pins are marked so hopefully nobody blows up their Tilty by attaching any 5v devices to 3.3v only pins.
